If one purges the Judaism of the Prophets and Christianity as Jesus Christ taught it of all subsequent additions, especially those of the priests, one is left with a teaching which is capable of curing all the social ills of humanity.

Leibnitz believed he saw the image of creation in his binary arithmetic in which he employed only two characters, unity and zero. Since God may be represented by unity, and nothing by zero, he imagined that the Supreme Being might have drawn all things from nothing, just as in the binary arithmetic all numbers are expressed by unity with zero. This idea was so pleasing to Leibnitz, that he communicated it to the Jesuit Grimaldi, President of the Mathematical Board of China, with the hope that this emblem of the creation might convert to Christianity the reigning emperor who was particularly attached to the sciences.

Our abiding belief is that just as the workmen in the tunnel of St. Gothard, working from either end, met at last to shake hands in the very central root of the mountain, so students of nature and students of Christianity will yet join hands in the unity of reason and faith, in the heart of their deepest mysteries.

The so-called Marxian dialectic is simply an effort by third-rate men to give an air of profundity to balderdash. Christianity has gone the same way. There are some sound ideas in it, but its advocates always add a lot of preposterous nonsense. The result is theology.

Truth can only be found by the human intellect, exercised in perfect freedom, and trained to submit itself to the facts of nature. This is the essence of the Scientific Method, which is the exact opposite of the Theological Method. Science teaches men to think with absolute independence of all arbitrary authority, but to submit all their thoughts to the test of actual experiences of Nature. Christianity teaches them to think only according to its own foregone dogmatic conclusions, and to stick to these dogmatic conclusion in defiance of all possible experience.

In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion.
